This is a [COMET](https://github.com/Unbabel/COMET) quality estimation model by Unbabel: It receives a source sentence and the respective translation and returns a score that reflects the quality of the translation.

# Usage for Inference Endpoint

```python
import json
import requests

API_URL = ""
API_TOKEN="MY_API_KEY"
headers = {
    "Authorization": f"Bearer {API_TOKEN}",
    "Content-Type": "application/json",
}

def query(url, headers, payload):
    data = json.dumps(payload)
    response = requests.request("POST", url, headers=headers, data=data)
    return json.loads(response.content.decode("utf-8"))

payload = {
    "inputs": {
        "batch_size": 8,
        "workers": None,
        "data": [
            {
                "src": "Youll be picking fruit and generally helping us do all the usual farm work",

            },{

# Intended uses

Unbabel's model is intented to be used for **reference-free MT evaluation**. 

Given a source text and its translation, outputs a single score between 0 and 1 where 1 represents a perfect translation. 

# Languages Covered:

This model builds on top of InfoXLM which cover the following languages:

Afrikaans, Albanian, Amharic, Arabic, Armenian, Assamese, Azerbaijani, Basque, Belarusian, Bengali, Bengali Romanized, Bosnian, Breton, Bulgarian, Burmese, Burmese, Catalan, Chinese (Simplified), Chinese (Traditional), Croatian, Czech, Danish, Dutch, English, Esperanto, Estonian, Filipino, Finnish, French, Galician, Georgian, German, Greek, Gujarati, Hausa, Hebrew, Hindi, Hindi Romanized, Hungarian, Icelandic, Indonesian, Irish, Italian, Japanese, Javanese, Kannada, Kazakh, Khmer, Korean, Kurdish (Kurmanji), Kyrgyz, Lao, Latin, Latvian, Lithuanian, Macedonian, Malagasy, Malay, Malayalam, Marathi, Mongolian, Nepali, Norwegian, Oriya, Oromo, Pashto, Persian, Polish, Portuguese, Punjabi, Romanian, Russian, Sanskri, Scottish, Gaelic, Serbian, Sindhi, Sinhala, Slovak, Slovenian, Somali, Spanish, Sundanese, Swahili, Swedish, Tamil, Tamil Romanized, Telugu, Telugu Romanized, Thai, Turkish, Ukrainian, Urdu, Urdu Romanized, Uyghur, Uzbek, Vietnamese, Welsh, Western, Frisian, Xhosa, Yiddish.

Thus, results for language pairs containing uncovered languages are unreliable!
